Monitoring Enclosure monitoring system CMC III The CMC III monitoring system controls the climate inside the enclosure. The user specifies limits for his equipment inside the enclosure. These are fully automatically monitored by the CMC III system. If a limit is exceeded, the CMC III can report this to the service team via e-mail or SMS. Counteractive action may also be initiated automatically. The system may also be connected to the customer network (via OPC/SNMP) to generate messages or values directly in the control room system (SCADA/BMS/NMS). The basic unit contains the principal sensors and may be extended via the integral CAN bus. The CMC III system is plug & play-ready, sensors are detected automatically, and the Web user interface is easy to use even with no programming knowledge. The power supply is 24 V DC with a redundant design. The system may also be supplied via the integral Power over Ethernet (PoE). The benefits of this system lie in its high level of reliability with automatic, direct initiation of counteractive action. Ever more complex applications are monitored by ever fewer person- nel. Staff may therefore rely on automated solutions to assist them in their duties and responsibilities. Applications: Temperature monitoring Humidity monitoring Filter mat/fan monitoring via air flow sensor, analog (m/s) with limits or speed control. Cold aisle housing/raised floor monitoring via differential pressure sensor, analog (Pa) with limits. Air control/regulation Heating control/regulation CMC III switches climate control unit off automatically when the enclosure door is open CMC III reports malfunctions in the event of a defective climate control unit CMC III opens the enclosure doors automatically in the event of a failure in the climate control system and uses the ambient air CMC III switches off the system in the event of overheating or shuts down a server in a controlled manner Note: For further information see Catalogue 33, page 768 – 777.
